CAP FOR BOTTLES OR SIMILAR RECEPTACLES.

SPECIFICATION forming part of Letters Patent No. 600,309, dated March 8,1898.

Application filed September 30, 1897. Serial No. 6531547. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDMOND GALLET, acitizen of the Republic of France,residing at Paris, in said Republic of France, have invented certain newand useful Improvements in or Relating to Caps for Bottles or SimilarReceptacles, of which the following is a specification.

This invention has for its object an improved cap or capsule forbottles, flasks, and similar receptacles arranged so that it mustnecessarily be broken when the bottle is opened, while it may have theappearance of a skin or parchment cap such as is often used for scentand other bottles.

-In order to make the invention better understood, the different stagesof manufacture of a cap according to the present invention areillustrated by way of example in the accompanying drawings, in which-Figure 1 is a mandrel on which my improved caps are shaped while theyare still in a soft condition. Fig. 2 is a side view of the cap afterthe same has been shaped on the mandrel. Fig. 3 is a vertical centralsection showing a cap placed in position on the stopper of a bottle, andFig. 4: is a side elevation of a bottle with my improved cap applied tothe neck and stopper of the same.

Similar letters of reference indicate corresponding parts.

The characteristic feature of the cap according to the present inventionconsists in the use of a compound having a basis of gelatin preferablyrendered opaque by any suitable substance and subjected after havingbeen placed on the bottle to the action of a reagent which hardens itand enables it to resist heat and humidity.

The process may be carried out as follows: First, a paste is preparedcontaining the following substances: gelatin, glycerin, oXid of zinc,sugar, and water. The proportions may be, for instance, as follows:water, four hundred to seven hundred parts; gelatin, two hundred to fourhundred parts; glycerin, thirty to sixty parts; oxid of zinc, onehundred to three hundred parts; sugar, fifty to one hundred parts.

To manufacture the caps, a core or former A, Fig. 1, is used, having theshape of the neck of a bottle, and may be provided with an engraving orornamentation either to render the appearance of the cap more attractiveor to produce a trade or other mark. The core A is dipped into the hotpaste, withdrawn, and cooled. The part of the core which has been dippedinto the paste thereby becomes covered with a film, which after coolingre tains its elasticity. The cap is then removed from the core and maybe turned inside out, if necessary, either in removing it from the coreor afterward. The cap then has the shape shown in Fig. 2, and theinscription or ornamentation engraved on the cores in intaglio appear onthe cap in relief. The top a of the cap is then provided with a hole b,much smaller than the plug a of the ground stopper to be used. The plugcan enter the hole I), owing to the elasticity of the material of thecap, which immediately afterward contracts again and fits around thereduced upper portion of the stopper, as shown in Fig. 3. When thestopper is thus provided with its cap, it is introduced into the bottleto be stoppered, the lower part of the cap embracing the neck of thebottle, Fig. 4. Then the cap is hardened, so as to enable it to resistthe action of heat and humidity. This may be efiected by subjecting thecap in place on the bottle to the action of any suitable reagent, formicaldehyde being particularly suitable and giving excellent results. Afterthis operation it is absolutely impossible to withdraw the stopper fromthe bottle without breaking the cap. In this manner a safety cllpsingdevice is obtained for bottles and the li e.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A safety-cap for bottles, consisting of a hardenedfilm provided with an opening in its upper portion or web, and fittingsnugly around the stopper-neck, bottle-mouth and bottle-neck,substantially as set forth.

2. A safety-cap for bottles, consisting of a film composed of a hardenedmixture of gelatin, glycerin and a pigment, substantially as set forth.

3. The process for making safety-caps for bottles, which consists first,in preparing an elastic paste containing gelatin; second,gath- Intestimony whereof I have signed this ering a film of said paste upon acore or former; specification in the presence of two subscribthird,removingit from said former; fourth, ing Witnesses.
